Hi List,
i've tried using flashrom for reading the SPI Flash of my Thinkpad X60s. It seems like it is using the (yet) unsupported M25P80.RES. I've added the few lines required to get it working, and at least reading the NVM works. Haven't tried writing the Flash (yes, i know about the risk regarding EC and friends) ;-)
